Disk
drive
module
Sometimes
you
can
exchange
a
faulty
disk
drive
module
without
the
assistance
of
a
service
representative.
You
can
do
this
only
if:
v
You
are
authorized
by
your
organization.
v
You
have
the
correct
disk
drive
module.
Figure
42
shows
the
disk
drive
module
for
the
2104
Model
DS4
or
Model
TS4.
The
front
of
the
disk
drive
module
has
a
handle
1
that
you
can
pull
up
to
open.
Verify
the
size
of
the
disk
drive
module.
The
size
of
a
disk
drive
module
is
on
the
label
2
at
the
front
of
the
disk
drive
module.
Attention:
v
Disk
drive
modules
are
fragile.
Handle
them
with
care.
Keep
them
well
away
from
strong
magnetic
fields.
v
Any
slot
that
has
no
disk
drive
module
installed
must
contain
a
dummy
disk
drive
module.
The
dummy
module
ensures
that
the
correct
airflow
is
maintained
around
the
disk
drive
modules
in
the
other
slots.
If
a
slot
remains
empty,
overheating
might
occur.
You
do
not
need
to
remove
power
from
the
2104
Model
DS4
or
Model
TS4
when
you
exchange
a
disk
drive
module.
